[Stackoverflow] [Progress OpenEdge ABL] Multiple OR operators in a single IF

[sander]

How to have multiple OR operators in a single if statement? I tried this way but there's an error of:

Incompatible data types in expression or assignment.
​

I looked at documentation of length function and it is LENGTH ( {string | raw-expression | blob-field } [ , type ] )?

Here's the code:

DEFINE VARIABLE cMonth AS CHARACTER.
DEFINE VARIABLE cDay AS CHARACTER.
DEFINE VARIABLE cYear AS CHARACTER.

UPDATE cDateFromUser.

cDay = (SUBSTRING(cDateFromUser,1,2)).
cMonth = (SUBSTRING(cDateFromUser,3,2)).
cYear = (SUBSTRING(cDateFromUser,5,4)).

IF (LENGTH(iDay <> 2)) OR (LENGTH(iMonth <> 2)) OR (LENGTH(iYear <> 4)) THEN DO:
/*Code*/
END.
ELSE DO:
/*Code*/
END.
